Common use of Cumulative Impacts of the Alternatives Clause in Contracts

Cumulative Impacts of the Alternatives. The present state of groundwater resources within the spatial scope of analysis is essentially a result of the area’s surface soil characteristics, underlying geology, and past and present actions, particularly past surface mining operations. These effects are described in Section 3.7.1. RFFAs within the spatial scope of analysis include ▇▇▇▇▇▇▇-▇▇▇▇▇▇ Mining Company’s permitted mining operations on federal lease tract OKNM 108097 and mining operations on the private coal tract to the north of the LBA tract. Groundwater related effects associated with mining operations on these tracts (totaling approximately 4,680 acres) are expected to be approximately the same as the effects described for the action alternatives. This is because the target coal seam in these tracts is the same as the LBA tract, these mining activities are subject to the same regulatory requirements as mining on the LBA tract, and the mining method on these tracts is the same as that which would be employed to mine the LBA tract. However, mining operations on adjacent tracts have no potential to effect groundwater quality or quantity around Club Lake because these operations would not occur under or in close proximity to Club Lake. Leasing and mining the LBA tract under the Proposed Action or Alternative C would result in an additional 1,270 acres or 940 acres, respectively, of underground mining activity on top of the 4,680 acres of reasonably foreseeable future underground mining activity represented by anticipated mining on the OKNM 108097 federal lease tract and on the private coal tract. Implementation of the Proposed Action or Alternative C would result in a cumulative total contiguous area of underground mining activity of 5,950 acres (under the Proposed Action) or 5,620 acres (under Alternative C), respectively. However, because the hydrogeologic setting in the area is such that aquifers beneath the LBA tract and adjacent land are probably isolated, mining on the LBA tract would not contribute, incrementally, to groundwater related effects associated with mining adjacent tracts.

Cumulative Impacts of the Alternatives. The present state of groundwater resources Past mining activity within the spatial scope of analysis is essentially has not included the employment of underground mining methods. As a result result, there are no existing surface effects from underground mining in this area. In addition, there are no ongoing underground mining activities occurring within the spatial scope of analysis at the area’s surface soil characteristics, underlying geology, and past and present actions, particularly past surface mining operations. These effects are described in Section 3.7.1moment. RFFAs within the spatial scope of analysis include ▇▇▇▇▇▇▇-▇▇▇▇▇▇ Mining Company’s permitted consist of anticipated underground (room and pillar) mining operations on the OKNM 108097 federal lease tract OKNM 108097 (approximately 2,380 acres) to the west of the LBA tract and mining operations on the private coal tract (approximately 2,300 acres) to the north of the LBA tracttract (Map 4). Groundwater related Surface effects associated with from mining operations on these tracts using room and pillar mining methods, possibly to include pillar removal (totaling approximately 4,680 acresretreat) are expected to mining, would be approximately the same as the effects those described above for the action alternatives. This is because the target coal seam in these tracts is the same as the LBA tract, these mining activities are subject to the same regulatory requirements as mining on the LBA tract, and the mining method on these tracts is the same as that which would be employed to mine the LBA tract. However, mining operations on adjacent tracts have no potential to effect groundwater quality or quantity around Club Lake because these operations would not occur under or in close proximity to Club Lake.

Implementation of the Proposed Action or Alternative C would result in a cumulative total contiguous area of underground mining activity of 5,950 acres (under the Proposed Action) or 5,620 acres (under Alternative C), respectively. HoweverThe cumulative surface effects of mining these areas using room and pillar mining methods, because possibly including pillar removal (retreat) mining, would be the hydrogeologic setting same as those described above for the action alternatives for reasons articulated in the area is such that aquifers beneath the LBA tract and adjacent land are probably isolated, mining on the LBA tract would not contribute, incrementally, to groundwater related effects associated with mining adjacent tractsprevious paragraph.

Cumulative Impacts of the Alternatives. The present state of groundwater resources surface water features within the spatial scope of analysis is essentially a result of the area’s surface soil characteristicsnatural topography, underlying geologyland uses (largely pasture and forested open space with some scattered dwellings), and past and present actions, particularly past surface mining operationsoperations and the creation of Club Lake in the 1940s. These effects are described in Section 3.7.13.6.1. RFFAs within the spatial scope of analysis include ▇▇▇▇▇▇▇-▇▇▇▇▇▇ Mining Company’s permitted mining operations on federal lease tract OKNM 108097 and mining operations on the private coal tract to the north of the LBA tract. Groundwater Surface water related effects associated with mining operations on these tracts (totaling approximately 4,680 acres) are expected to be approximately the same as the effects described for the action alternatives. This is because the target coal seam in these tracts is the same as the LBA tract, these mining activities are subject to the same regulatory requirements as mining on the LBA tract, and the mining method on these tracts is the same as that which would be employed to mine the LBA tract. However, mining operations on adjacent tracts have no potential to effect groundwater affect surface water quality or quantity around in Club Lake because these operations would not occur under or in close proximity to outside the Club LakeLake surface-water basin. Leasing and mining the LBA tract under the Proposed Action or Alternative C would result in an additional 1,270 acres or 940 acres, respectively, of underground mining activity on top of the 4,680 acres of reasonably foreseeable future underground mining activity represented by anticipated mining on the OKNM 108097 federal lease tract and on the private coal tract.
